Discrete Level Indicators: Switches To Keep Your Operation Afloat

a row of stainless steel floatsYou have liquid in containers, and you need to keep track of the liquid in those containers. You already know that liquid level measurements come in two types: continuous measurements that give on-going feedback about the level of the liquid being measured, and discrete measurements that give, essentially, a Yes or No answer to the question, "Is the liquid at this particular level?" But which technology type is the right one for you? Your liquids don’t require "up-to-the-minute" monitoring, you just need to know when "critical levels" are reached. Congratulations, you need a float switch!

Float Switches in the Food and Beverage Industry

Deep Fat FryerFloat switches are used for point-level detection and are commonly used to control other devices such as alarms and pumps when a liquid level rises or falls to a specific point. APG’s Stainless Steel Float Switches are used in a variety of industries and applications including applications in food and beverage, water and wastewater, and chemical industries. APG’s Stainless Steel Float Switches feature NSF 169 approval making them a great selection for food and beverage applications. Below are examples of food and beverage industry applications APG’s Float Switches are used in.

The Basics of Float Switches

A float switch is a type of contact liquid level sensor that uses a float to operate a switch. Float switches are commonly used to control other devices such as alarms and pumps when a liquid level rises or falls to a specific point. While there are some mechanical float switches (similar to the float in a toilet tank that turns off the incoming water when the tank is “full”), this article will focus on electrical float switches, floats that are used to open and close (i.e., turn off and on) electrical circuits.

The APG Float Switch Advantage

The APG Vertical Float Switch Advantage

While APG’s Stainless Steel Float Switches might look like your average float switch at first glance, the truth is they are far from being JUST another float switch. APG’s Stainless Steel Float Switches have unparalleled repeatability in actuation and 100% repeatability of float position. To achieve this, APG’s Stainless Steel Horizontal Float Switches and Vertical Float Switches are expertly engineered, from the electrical components to the stainless steel shell, providing greater accuracy and a longer sensor life span that is simply not found in other float switches on the market.

How to Configure Your Float Switch: Normally Open Switches vs Normally Closed Switches

normally open vs normally closedDeciding whether your float switch needs to be normally open or normally closed for pump control can be a little confusing. So we would like to clear things up.

When we say normally open or normally closed, we are referring to an electrical circuit. An open circuit is incomplete, meaning that the electric current is unable to complete the loop due to a gap. A closed circuit is complete with no gaps, enabling the current to travel through the whole loop. 

APG Announces FS-410-HT High Temperature Upgrade

APG's Series FS-410 Miniature Stainless Steel Float Switches, now with High Temperature ranges

LOGAN, UT – Automation Products Group, Inc. (APG) announces the FS-410-HT, a high temperature upgrade for the Series FS-410 Miniature Stainless Steel Vertical Float Switch.

Series FS-410 are already versatile switches, compatible with a wide range of liquids and pressures, and carrying CSA and NSF certifications. And now, with the High Temperature option, FS-410-HTs can handle up to 500° F (260° C)! No one else on the market can match 100 W and 500° F in a switch that’s just over 2.3”.

APG Introduces the new Series FS-500 Stainless Steel Horizontal Float Switches

APG's New Series FS-500 Stainless Steel Horizontal Float Switches

LOGAN, UT – Automation Products Group, Inc. (APG) introduces the new Series FS-500 Stainless Steel Horizontal Float Switch.

Series FS-500 are durable, versatile float switches with a wide range of usage and applications. Three fitting configurations and two temperature ranges—all carrying CSA approvals—make the Series FS-500 an easy choice for OEM, water and wastewater, and chemical applications. Series FS-500 switches are rated for 100 W at both Standard Temperature (up to 368° F / 187° C) and High Temperature (500° F / 260° C) ranges. With their compact size, stainless steel wetted materials, and reversible switch orientation, FS-500 switches are go-anywhere, use-everywhere horizontal float switches

Three Advantages Gained By Using the FS-400 Vertical Stainless Steel Float Switch

liquid storage tanks in a fieldEverybody is looking for an advantage. Business are constantly trying to get a leg up on their competitors on performance, quality, or reliability (or all three!). And it is often in the small things, the details, where these advantages can be won and lost. Float switches are, by nature, small things, but the right float switch can give you tremendous advantages. Take the FS-400 Stainless Steel Vertical Float Switch, for instance. Compared to other float switches, the FS-400 has several advantages. Let’s take a look at three.

Excel in Small Space Level Monitoring with the FS-410

Night lights at an oil refineryMany things in life come with trade-offs, often on a size-versus-functionality continuum. At one end, extreme size dictates reduced functionality; similarly, optimum functionality necessitates specific sizes. This works for vehicles—maximizing for speed or cargo requires size constraints—and it is often the case in level monitoring. However, level monitoring in tight spaces doesn’t have to mean sacrificing quality. The new Series FS-410 Miniature Stainless Steel Vertical Float Switch is made to provide big performance in small spaces.

APG Introduces the new Series FS-400 and FS-410 Stainless Steel Vertical Float Switches

APG's New Series FS-400 and FS-410 Stainless Steel Vertical Float Switches

LOGAN, UT – Automation Products Group, Inc. (APG) introduces two new float switches, the Series FS-400 Stainless Steel Vertical Float Switch, and the Series FS-410 Miniature Stainless Steel Vertical Float Switch.

The Series FS-400 and FS-410 are versatile switches, compatible with a wide range of liquids, temperatures, and pressures. They feature all stainless steel wetted materials, user-reversible logic function, and high operating temperature ranges. With max capacities of 60 W and 30 W respectively, the FS-400 and FS-410 can both handle up to 120 VDC or 240 VAC. Installation is simple with NPT mounting and a hex nut. The Series FS-400 Stainless Steel Vertical Float Switch and Series FS-410 Miniature Stainless Steel Vertical Float Switch offer set-and-forget ease of use in all the places you need them.
